PORTLAND, Ore., June 16, 2010 – While fewer new homes were built in the past year in the Portland metropolitan area than in the previous year, the market share of third party certified homes increased. Twenty three percent (23%) of all newly constructed homes in the Portland metropolitan area sold between May 1, 2009 and April 30, 2010 received a third party certification. This finding is based upon data reported by the Portland area RMLS to Earth Advantage Institute.

The term “certified home” refers to homes that received an Earth Advantage, Energy Star, or LEED for Homes designation, or a combined Earth Advantage/Energy Star designation. Certification and sales information is reported by participating real estate brokers to RMLS. The Portland metropolitan area region includes Multnomah, Clackamas, Columbia, Washington and Yamhill Counties in Oregon and Clark County in Washington.

This finding continues a three year trend in which the market share of certified homes in the Portland region has increased. Please see Table One below for detail.

 “As energy efficiency and healthier homes gain more attention, builders and homeowners increasingly place value on home certification,” said Sean Penrith, executive director, Earth Advantage Institute. “It is very encouraging to see the market share of certified homes continue to rise over the past three years despite the difficulties in residential markets.”
